ixgbevf: Link lost in VM on ixgbevf when restoring from freeze or suspend

Browse Source 
This patch fixed issue in VM which shows no link when hypervisor is
restored from low-power state. The driver is responsible for re-enabling
any features of the device that had been disabled during suspend calls,
such as IRQs and bus mastering.
